the engine from overheating and becoming dama-
ged.
The starter cord must be renewed if it shows any
sign of wear.
Clutch group (20)
The clutch bell housing must b kept free from saw
chips and dirt by removing the clutch cover after
completing work and blowing out the clutch with
compressed air. Your dealer must lubricate the in-
side bearing after every 30 operating hours.
Chain brake
Regularly check the function of the chain brake
and that the metal band around the clutch bell
housing is undamaged. Do this by removing the
cover after completing work and then reinstalling
it correctly.
The band must be replaced if the thickness at the
contact points with the clutch bell is reduced to
approx. half of its thickness at the two ends, which
are not exposed to wear.
Chain sprocket
The condition of the pinion must be checked re-
gularly by the dealer and it must be renewed if the
wear exceeds the permitted amount.
Do not install a new chain on a worn chain spro-
cket or vice versa.
Lubricating hole (21)
Regularly remove the cover, remove the bar and
check that the lubricating holes of the machine (1)
and the bar (2) are not blocked.
Chain interception bolt
This bolt is an important safety element because
it prevents uncontrolled movements of the chain
if it breaks or becomes loose.
Regularly check the condition of the bolt and re-
pair it if damaged.
Fastenings
Regularly check that all fastening screws and nuts
are firms seated, and that all hand grips are firmly
attached.
Cleaning the air filter (22)
CAUTION!
Cleaning the air filter is a prerequisite for
correct operation and a long service life
of the machine. To avoid irreparable da-
mage to the engine, do not work without
a filter, or if the filter is damaged.
50
Cleaning should be carried out after
every 15 hours of machine use.
To clean the filter:
1. Unscrew the rotary cap (1).
2. Remove the cover (2) and filter element (3).
3. Strike the filter element (3) lightly to remove
dirt, and clean it with low-pressure compres-
sed air if necessary.
CAUTION!
Never wash the filter element (3).
Replace it if it becomes too dirty or
is damaged.
4. Mount the filter element (3) and cover (2)
again.
5. Screw the rotary cap (1) back on.
Checking the spark plug (23)
The spark plug can be accessed by removing the
cover of the air filter.
1. Regularly remove the spark plug and clean off
any deposits using a small metal brush.
2. Check the electrode gap and re-establish the
correct dimension if necessary.
3. Reinsert the spark plug and use the supplied
spanner to tighten it as far as the stop.
The spark plug must be renewed using
an equivalent spark plug with correspon-
ding properties if the electrodes have
burned out or the insulation is damaged.
In any event, renew it every 100 opera-
ting hours.
Carburettor setting
The carburettor is set at the factory so that ma-
ximum performance will be achieved in any ope-
rating situation, with minimum harmful exhaust
emissions and in accordance with the applicable
standards.
If the performance is poor, make sure in advance
that the chain can run freely and that the bar does
not have worn guides; contact your dealer to have
the carburettor performance and engine checked.
Idling speed setting
The chain is not allowed to move when the engine
is idling. If the chain does move when the engine
is idling, you will have to contact your dealer in
order to achieve the correct engine setting.
